Abstract
The utility model discloses a simplified secondary ejection structure applied to an injection mold. The simplified secondary ejection structure comprises an ejector plate, an insert and a rear mold which are arranged in the injection mold, an ejector is arranged on the ejector plate, the insert and the ejector penetrate the rear mold to the top, the lower part of the insert penetrates the ejector plate, the bottom of the insert is elastically connected with the baseplate of the injection mold through a spring, and a flange, whose position is limited by the bottom surface of the rear mold, is formed at the lower part of the insert. The simplified secondary ejection structure is simple and reasonable in structure, solves the problem that a barbed product is difficult to demold and is widely applied to injection molds.
Description
Technical field
The utility model relates to a kind of injection mold, particularly a kind of reduced form secondary ejecting structure that is applied to injection mold.
Background technology
Product for some injection mo(u)ldings, wall can design back-off within it according to demand, because this constructed products depanning is difficult, in design for Injection Mould, be not easy to do the row position, the mould structure that needs secondary to eject, common secondary ejecting structure have two groups of (four) ejector retainner plates, cause big, the complex structure of mould volume, at above-mentioned shortcoming, be necessary to make improvement.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of simple and reasonable for structure that the utility model provides, and is convenient to the reduced form secondary ejecting structure that is applied to injection mold of product secondary ejection device.
The technical scheme that its technical problem that solves the utility model adopts is:
Be applied to the reduced form secondary ejecting structure of injection mold, comprise the ejector retainner plate, mold insert and the back mould that are arranged in the injection mold, described ejector retainner plate is provided with thimble, described mold insert and thimble are worn to mould top, back, this mold insert bottom is passed ejector retainner plate and the bottom is connected with the base plate elasticity of injection mold by spring, and described mold insert bottom is provided with and is subjected to the spacing flange in mould bottom surface, back.
The beneficial effects of the utility model are: after the product die sinking, at first ejector retainner plate up ejects under the effect of injection machine, because ejector retainner plate reduces the pressure to mold insert bottom spring gradually in the process on last top, mold insert ejects under the elastic reset of spring up, after the flange of mold insert bottom is subjected to the mould bottom surface spacing after, make mold insert stop to eject, this moment, product was ejected the back mould in the injection mold, and ejector retainner plate continues product is ejected under the effect of injection machine, thereby product is broken away from mold insert fully, finish the knockout course of product; In the said process owing to be the back mould that earlier product is ejected injection mold by mold insert, utilize thimble that product and mold insert are broken away from again, make product with the mold insert detach procedure in produce the unlikely damage of elastic deformation and the demoulding smoothly, the utility model is simple and reasonable, has solved the problem of inner wall belt overhead kick product stripping difficulty.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, be applied to the reduced form secondary ejecting structure of injection mold, comprise the ejector retainner plate 1, mold insert 2 and the back mould 7 that are arranged in the injection mold, described ejector retainner plate 1 is provided with thimble 6, described mold insert 2 is worn to mould 7 tops, back with thimble 6, these mold insert 2 bottoms are passed ejector retainner plate 1 and the bottom are connected with base plate 4 elasticity of injection mold by spring 3, and described mold insert 2 bottoms are provided with and are subjected to the spacing flange 5 in mould 7 bottom surfaces, back.
Operation principle of the present utility model is: after product 8 die sinkings, at first ejector retainner plate 1 up ejects under the effect of injection machine, because ejector retainner plate 1 reduces the pressure to mold insert 2 bottom springs 3 gradually in the process on last top, mold insert 2 ejects under the elastic reset of spring 3 up, after the flange 5 of mold insert 2 bottoms is subjected to mould 7 bottom surfaces spacing after, make mold insert 2 stop to eject, this moment, product 8 was ejected the back mould 7 in the injection mold, and ejector retainner plate 1 continues product is ejected under the effect of injection machine, thereby product 8 is broken away from mold insert 2 fully, finish the knockout course of product 8; In the said process owing to be the back moulds 7 that earlier product ejected injection mold by mold insert 2, utilize thimble that 1 product 8 and mold insert 2 are broken away from again, make product 8 with mold insert 2 detach procedures in produce the unlikely damage of elastic deformation and the demoulding smoothly, the utility model is simple and reasonable, having solved the problem of inner wall belt overhead kick product stripping difficulty, is a kind of reduced form secondary ejecting structure that is widely used in injection mold.
Claims (1)
